BACKGROUND

1. Field

This disclosure relates generally to compounds, pharmaceutical compositions and methods of use of the compounds and compositions containing them. This disclosure relates more particularly to certain carboxamide compounds and pharmaceutical compositions thereof, and to methods of treating and ameliorating disorders and conditions related to oxidative stress, mitochondrial dysfunction, free radical damage and metabolic inefficiency, among others.

2. Technical Background

Adiponectin is a protein hormone exclusively expressed in and secreted from adipose tissue and is the most abundant adipose-specific protein. Adiponectin has been implicated in the modulation of glucose and lipid metabolism in insulin-sensitive tissues. Decreased circulating adiponectin levels have been demonstrated in some insulin-resistant states, such as obesity and type 2 diabetes mellitus and also in patients with coronary artery disease, atherosclerosis and hypertension. Adiponectin levels are positively correlated with insulin sensitivity, HDL (high density lipoprotein) levels and insulin stimulated glucose disposal and inversely correlated with adiposity and glucose, insulin and triglyceride levels. Thiazolidinedione drugs, which enhance insulin sensitivity through activation of the peroxisome proliferator-activated receptor-γ, increase endogenous adiponectin production in humans.

Adiponectin binds its receptors in liver and skeletal muscle and thereby activates the 5″-AMP-activated protein kinase (AMPK) pathway. Adiponectin receptors 1 and 2 are membrane-bound proteins found in skeletal muscle and liver tissue. Being a multi-substrate enzyme, AMPK regulates a variety of metabolic processes, such as glucose transport, glycolysis and lipid metabolism. It acts as a sensor of cellular energy homeostasis and is activated in response to certain hormones and muscle contraction as well as to intracellular metabolic stress signals such as exercise, ischemia, hypoxia and nutrient deprivation. Once activated, AMPK switches on catabolic pathways (such as fatty acid oxidation and glycolysis) and switches off ATP-consuming pathways (such as lipogenesis). Adiponectin improves insulin sensitivity by directly stimulating glucose uptake in adipocytes and muscle and by increasing fatty acid oxidation in liver and muscle, resulting in reduced circulating fatty acid levels and reduced intracellular triglyceride contents. Moreover, adiponectin decreases glycogen concentration by reducing the activity of glycogen synthase. Adiponectin also plays a protective role against inflammation and atherosclerosis. It suppresses the expression of adhesion molecules in vascular endothelial cells and cytokine production from macrophages, thus inhibiting the inflammatory processes that occur during the early phases of atherosclerosis.

The present disclosure contemplates combinations of particularly described embodiments. For example, paragraph [0013] discloses certain embodiments of ring system “B” and paragraph [0015] discloses certain embodiments of T; also contemplated are embodiments in which ring system “B” is as described as in paragraph [0013], and T is as described in paragraph [0015]. This disclosure contemplates all such combinations, to the extent the definitions of the various structural features do not conflict with one another.

For simplicity, chemical moieties are defined and referred to throughout primarily as univalent chemical moieties (e.g., alkyl, aryl, etc.). Nevertheless, such terms are also used to convey corresponding multivalent moieties under the appropriate structural circumstances clear to those skilled in the art. For example, while an “alkyl” moiety can refer to a monovalent radical (e.g. CH₃—CH₂—), in some circumstances a bivalent linking moiety can be “alkyl,” in which case those skilled in the art will understand the alkyl to be a divalent radical (e.g., —CH₂—CH₂—), which is equivalent to the term “alkylene.” (Similarly, in circumstances in which a divalent moiety is required and is stated as being “aryl,” those skilled in the art will understand that the term “aryl” refers to the corresponding divalent moiety, arylene). All atoms are understood to have their normal number of valences for bond formation (i.e., 4 for carbon, 3 for N, 2 for O, and 2, 4, or 6 for S, depending on the oxidation state of the S). Nitrogens in the presently disclosed compounds can be hypervalent, e.g., an N-oxide or tetrasubstituted ammonium salt. On occasion a moiety may be defined, for example, as (A)_(a)-B—, wherein a is 0 or 1. In such instances, when a is 0 the moiety is B— and when a is 1 the moiety is A-B—.

As used herein, the term “alkyl” includes alkyl, alkenyl and alkynyl groups of a designed number of carbon atoms, desirably from 1 to about 12 carbons (i.e., inclusive of 1 and 12). The term “C_(m)-C_(n) alkyl” means an alkyl group having from m to n carbon atoms (i.e., inclusive of m and n). The term “C_(m)-C_(n) alkyl” means an alkyl group having from m to n carbon atoms. For example, “C₁-C₆ alkyl” is an alkyl group having from one to six carbon atoms. Alkyl and alkyl groups may be straight or branched and depending on context, may be a monovalent radical or a divalent radical (i.e., an alkylene group). In the case of an alkyl or alkyl group having zero carbon atoms (i.e., “C₀ alkyl”), the group is simply a single covalent bond if it is a divalent radical or is a hydrogen atom if it is a monovalent radical. For example, the moiety “—(C₀-C₆ alkyl)-Ar” signifies connection of an optionally substituted aryl through a single bond or an alkylene bridge having from 1 to 6 carbons. Examples of “alkyl” include, for example, methyl, ethyl, propyl, isopropyl, butyl, iso-, sec- and tert-butyl, pentyl, hexyl, heptyl, 3-ethylbutyl, 3-hexenyl and propargyl. If the number of carbon atoms is not specified, the subject “alkyl” or “alkyl” moiety has from 1 to 12 carbons.

The term “haloalkyl” is an alkyl group substituted with one or more halogen atoms, e.g. F, Cl, Br and I. A more specific term, e.g., “fluoroalkyl” is an alkyl group substituted with one or more fluorine atoms. Examples of “fluoroalkyl” include fluoromethyl, difluoromethyl, trifluoromethyl, pentafluoroethyl, hexafluoroisopropyl and the like. In certain embodiments of the compounds disclosed herein, each haloalkyl is a fluoroalkyl.

The term “aryl” represents an aromatic ring system having a single ring (e.g., phenyl) which is optionally fused to other aromatic hydrocarbon rings or non-aromatic hydrocarbon rings. “Aryl” includes ring systems having multiple condensed rings and in which at least one is carbocyclic and aromatic, (e.g., 1,2,3,4-tetrahydronaphthyl, naphthyl). Examples of aryl groups include phenyl, 1-naphthyl, 2-naphthyl, indanyl, indenyl, dihydronaphthyl, fluorenyl, tetralinyl, and 6,7,8,9-tetrahydro-5H-benzo[a]cycloheptenyl. In certain examples, aryl groups include those having a first carbocyclic, aromatic ring fused to an aromatic or aliphatic heterocycle, for example, 2,3-dihydrobenzofuranyl. The aryl groups herein are unsubstituted or, when specified as “optionally substituted”, can unless stated otherwise be substituted in one or more substitutable positions with various groups, as described below.

The term “heteroaryl” refers to an aromatic ring system containing at least one heteroatom selected from nitrogen, oxygen and sulfur in an aromatic ring. The heteroaryl may be fused to one or more cycloalkyl or heterocycloalkyl rings.

The term “pharmaceutically acceptable salts” or “a pharmaceutically acceptable salt thereof” refer to salts prepared from pharmaceutically acceptable non-toxic acids or bases including inorganic acids and bases and organic acids and bases. If the compound is basic, salts may be prepared from pharmaceutically acceptable non-toxic acids. Such salts may be, for example, acid addition salts of at least one of the following acids: benzenesulfonic acid, citric acid, α-glucoheptonic acid, D-gluconic acid, glycolic acid, lactic acid, malic acid, malonic acid, mandelic acid, phosphoric acid, propanoic acid, succinic acid, sulfuric acid, tartaric acid (d, l, or dl), tosic acid (toluenesulfonic acid), valeric acid, palmitic acid, pamoic acid, sebacic acid, stearic acid, lauric acid, acetic acid, adipic acid, carbonic acid, 4-chlorobenzenesulfonic acid, ethanedisulfonic acid, ethylsuccinic acid, fumaric acid, galactaric acid (mucic acid), D-glucuronic acid, 2-oxo-glutaric acid, glycerophosphoric acid, hippuric acid, isethionic acid (ethanolsulfonic acid), lactobionic acid, maleic acid, 1,5-naphthalene-disulfonic acid, 2-naphthalene-sulfonic acid, pivalic acid, terephthalic acid, thiocyanic acid, cholic acid, n-dodecyl sulfate, 3-hydroxy-2-naphthoic acid, 1-hydroxy-2-naphthoic acid, oleic acid, undecylenic acid, ascorbic acid, (+)-camphoric acid, d-camphorsulfonic acid, dichloroacetic acid, ethanesulfonic acid, formic acid, hydriodic acid, hydrobromic acid, hydrochloric acid, methanesulfonic acid, nicotinic acid, nitric acid, orotic acid, oxalic acid, picric acid, L-pyroglutamic acid, saccharine, salicylic acid, gentisic acid, and/or 4-acetamidobenzoic acid.

The compounds described herein can also be provided in prodrug form. “Prodrug” refers to a derivative of an active compound (drug) that undergoes a transformation under the conditions of use, such as within the body, to release the active drug. Prodrugs are frequently, but not necessarily, pharmacologically inactive until converted into the active drug. Prodrugs are typically obtained by masking a functional group in the drug believed to be in part required for activity with a progroup (defined below) to form a promoiety which undergoes a transformation, such as cleavage, under the specified conditions of use to release the functional group, and hence the active drug. The cleavage of the promoiety can proceed spontaneously, such as by way of a hydrolysis reaction, or it can be catalyzed or induced by another agent, such as by an enzyme, by light, by acid, or by a change of or exposure to a physical or environmental parameter, such as a change of temperature. The agent can be endogenous to the conditions of use, such as an enzyme present in the cells to which the prodrug is administered or the acidic conditions of the stomach, or it can be supplied exogenously. A wide variety of progroups, as well as the resultant promoieties, suitable for masking functional groups in the active drugs to yield prodrugs are well-known in the art. For example, a hydroxyl functional group can be masked as a sulfonate, ester or carbonate promoiety, which can be hydrolyzed in vivo to provide the hydroxyl group. An amino functional group can be masked as an amide, carbamate, imine, urea, phosphenyl, phosphoryl or sulfenyl promoiety, which can be hydrolyzed in vivo to provide the amino group. A carboxyl group can be masked as an ester (including silyl esters and thioesters), amide or hydrazide promoiety, which can be hydrolyzed in vivo to provide the carboxyl group. Specific examples of suitable progroups and their respective promoieties will be apparent to those of skill in the art.

The compounds disclosed herein can also be provided as N-oxides.

The presently disclosed compounds, salts, prodrugs and N-oxides can be provided, for example, in solvate or hydrate form.

One of ordinary skill in the art of medicinal chemistry also will appreciate that the disclosed structures are intended to include isotopically enriched forms of the present compounds. As used herein “isotopes” includes those atoms having the same atomic number but different mass numbers. As will be apparent to those of skill in the art upon consideration of the present compounds, certain atoms can be enriched an isotope of that atom. For example, compounds having a fluorine atom, may be synthesized in a form enriched in the radioactive fluorine isotope ¹⁸F. Similarly, compounds may be enriched in the heavy isotopes of hydrogen, deuterium and tritium, and can be enriched in a radioactive isotope of carbon, such as ¹³C. Such compounds can be useful, for example, in studying the AMPK pathway and its role in metabolism.

Compounds can be assayed for binding to a membrane-bound adiponectin receptor by performing a competitive binding assay with adiponectin. In one such procedure, HEK 293 cellular membrane is coated onto a COSTAR 384 plate, which is then blocked with 1% casein. Polyhistidine-tagged globular adiponectin and a candidate compound is incubated with the membrane in HEPES buffer. Unbound ligands are washed away and the degree of binding of the adiponectin is determined using horseradish peroxidase-conjugated anti-polyhistidine. Compounds that compete with adiponectin binding to the membrane (i.e., give a reduced signal compared to a control performed without a candidate compound) can be chosen as hits and further screened using the below-described functional assays to identify adiponectin receptor agonists.

An in-cell western assay can be performed to demonstrate the activation of AMPK in human liver cells by globular adiponectin using glutathione S-transferase (GST). AMPK activity can be measured by the relative concentration of phosphorylated acetyl Co-A carboxylase, which is one of the products of AMPK. An increase in pACC correlates with an increase in the rate of fatty acid oxidation.

The compounds disclosed herein can be administered, for example, orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations containing one or more pharmaceutically acceptable carriers, diluents or excipients. The term parenteral as used herein includes percutaneous, subcutaneous, intravascular (e.g., intravenous), intramuscular, or intrathecal injection or infusion techniques and the like.

These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, can also be present.

Pharmaceutical compositions can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents can be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions can also contain sweetening and flavoring agents.

Syrups and elixirs can be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations can also contain a demulcent, a preservative, flavoring, and coloring agents. The pharmaceutical compositions can be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension can be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils can be employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The presently disclosed compounds can also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the compound with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.

The presently disclosed compounds can also be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle.

Male C57B/6J mice (8 weeks old) are randomly divided into at least four cohorts for exercise-trained and sedentary control and dosage groups.

Mice are acclimated to moderate treadmill running (10 m/min for 15 min) every other day for 1 week (day 1, 3, 5, 7). After acclimation, basal running endurances for the four groups are determined via a treadmill running test, where the speed is gradually increased from 0 to 15 m/min over the course of 15 min and then maintained constant until exhaustion. Treadmill to be used is 1012M-8-E52 Modular Enclosed Metabolic Treadmill for Mice, 8 Lanes w/Shock for Mice w/Shocker Detection & Software from Columbus Instruments or similar (with attached open-flow calorimeter for the measurement of respiratory metabolic performance while exercising). Exhaustion defined when mice are unable to avoid repetitive electrical shocks. Data are collected on total time and distance run as well as VO₂.

On day 8 dosing by gavage with the adiponectin receptor agonist begins for the sedentary and exercise-trained groups and dosing with vehicle only for the control sedentary and exercise-trained groups.

Beginning on day 9, the groups to be exercise-trained are subjected to 4 weeks (5 days/week) of exercise training During all exercise sessions and treadmill tests, VO₂ is measured before, during, and after exercise by means of indirect calorimetry in metabolic treadmill chambers. The 5th day of training for each weekly exercise regime is used as a complete treadmill test where the speed is gradually increased from 0 to 15 m/min over the course of 15 min and then maintained constant until exhaustion. Day 9 exercise to consist of treadmill running of 10 m/min for 15 min with a treadmill incline of 5 degrees. Subsequent exercise-training is to be progressive with increasing intensity and time (also incline of 5 degrees on treadmill). Data are collected on total time and distance for each training session, with point of exhaustion noted for mice failing to complete exercise.

Treatment with the present adiponectin receptor agonists results in increased endurance for both the exercise-trained and sedentary groups.
